The modern inflatable boat has long since ceased to be a beachside toy and has become a complete, reliable boat that can withstand severe stress and storm conditions, and its success is based on the use of polyvinyl chloride (PVC), a synthetic material that surpasses classical rubber in strength while maintaining the necessary elasticity. reinforcement With special threads, such vessels became light, but incredibly resistant to punctures and mechanical damage.
Choosing the right model is often a challenge, as the market is oversaturated with offers from dozens of manufacturers, each of which promises the perfect value for money. You will have to understand the types of bottom, material density and design nuances, so as not to overpay for unnecessary options or, conversely, not to buy too weak a vessel for the planned tasks. The service life of a high-quality PVC boat with proper care is 10-15 years, which makes it one of the most profitable investments in water-motor equipment. In this article, we will discuss in detail all aspects that will help you make an informed decision.
Materials and technology of production of the case
The basis of any inflatable boat is a dense fabric consisting of two or more layers of polyvinyl chloride, between which is laid a layer of polyester fabric. reinforcementIt's what gives the material the ability to hold high pressure without deformation. Unlike the old rubber models, modern PVC boats don't pull under load, which ensures course stability and controllability even on the wave.
The density of the fabric is measured in grams per square meter and usually varies in the range from 750 to 1150 g/m2. Many buyers mistakenly believe that the higher the density, the better, but for most tasks, a high-quality medium-density material is quite enough if it has the right threading. Excessive thickening of the walls of the cylinders only increases the overall weight of the boat, making it less convenient for carrying and assembly.
The most important stage of production is gluing of the seams, which is performed by hot vulcanization or using special two-component adhesives. Hot seam technology It is considered the most reliable, as it provides a monolithic connection that cannot be layered during operation. When buying, be sure to check the quality of the seams for the absence of bloating and unpatched areas.
⚠️ Note: The use of a boat with damaged seams or glue bloating is strictly prohibited, as this can lead to sudden depressurization of cylinders at depth.
A quality material should also be resistant to UV radiation and petroleum products. If you plan to fish with a gasoline engine, make sure that the outer shell has additional protection from random fuel droplets that can dissolve the top layer of cheap PVC.
Underfloor design: from sleigh to inflatable floor
Bottom type is perhaps the most important parameter that affects the performance and comfort of the boat. float-bottom (BND), which is a separate cylinder with an internal sling system that forms a plane, and these boats are very lightweight, they can be folded into a compact backpack, but they are less stable on planing and prone to breaking through underwater obstacles.
A more common option is a hard or folding slate mounted on inflatable tubes. Slate can be made of water-resistant plywood or aluminum alloy. Plywood flooring is cheaper and warmer, but afraid of prolonged contact with water and requires drying after each fishing. Aluminum structures are devoid of this drawback, they are stronger and more durable, but much heavier.
For lovers of high-speed riding and professional fishing, the best choice will be boats with a high-speed fishing. low-pressure They use a sling system that connects the upper and lower planes, which allows you to pump the bottom to a pressure of 1 atm or more, and this turns the bottom into a rigid slab that perfectly holds the shock wave and allows you to achieve high speeds.
- 🛶 inflatable floor (NDND) - maximum compactness in packaged form, ideal for hiking.
- 🪵 Plywood slate is an affordable price and ease of repair, but requires careful drying.
- 🔩 Aluminum flooring is high strength, does not rot, but has a large weight and high cost.
When choosing, pay attention to the presence of profiled beams that distribute the load from passengers and the engine. The absence of such reinforcements will lead to rapid wear of the fabric in the areas of contact with the seats and the engine.
Boat capacity and dimensions of the craft
Determining the necessary load capacity is a critical step on which your safety on the water depends. rated carrying capacity is specified by the manufacturer on the basis that the sides of the boat will rise above the water by at least 15-20 cm.
Not only the weight of the passengers, but also the weight of equipment, motor, fuel, battery and anchor, for example, for two people with a minimum set of fishermen and an outboard motor weighing 20 kg, the optimal boat will be a boat with a length of 320-340 cm. If you plan to bring a dog or additional equipment, it is better to consider models of 360 cm or more.
| Boat length (cm) | Load capacity (kg) | Max engine power (hp) | Capacity (person) |
|---|---|---|---|
| 280–290 | 220 | 5 | 1–2 |
| 320–330 | 350 | 10 | 2–3 |
| 350–360 | 450 | 15 | 3–4 |
| 380–400 | 600 | 20 | 4–5 |
It is worth remembering that the claimed capacity is often theoretical, and comfortable accommodation is usually one person less than the passport, especially when you consider the scope of the impact of rods or the need to move on a boat.
When calculating your load capacity, always add 15-20% of your planned weight to ensure buoyancy and safety.
Assembly and preparation for launching
Properly assembling a boat is a guarantee of long service and safety. Start the process by laying out the cylinders on a flat surface, removing sharp objects, stones and branches. In the cold season, allow the material to warm up if the boat was stored at negative temperatures, as PVC becomes brittle in the cold.
The cylinders should be pumped in stages using a high pressure pump (feather or electric) and first the cylinders are pumped to about 50% of the working pressure, then the slate is installed (if it is rigid), and only after that the final pumping is made to the norm specified in the instructions. 0.2-0.25 atm.
☑️ Checklist for boat assembly
Pay special attention to the installation of sleigh. Sheets should enter tightly, but without excessive effort, which can damage the fabric. After installing all the elements, be sure to check the tightness of the valves by covering them with lids. A loosely closed valve can cause gradual air venting during fishing.
⚠️ Warning: Never leave a fully pumped boat in direct sunlight for long periods of time unattended, as heating the air inside can cause the seams to rupture.
To control pressure, it is convenient to use a pressure gauge built into the pump or separate. Pumped cylinders lose elasticity and become more vulnerable to impact, and under-performed ones reduce the driving quality and stability of the vessel.
Operation and care of PVC boat
The care of an inflatable boat requires no complex manipulation, but it requires regularity. After each operation, especially in salt water or bodies of water with abundant vegetation, the boat must be washed with fresh water, which will help to wash away the aggressive salts and organics that can eventually destroy the structure of polyvinyl chloride.
Drying is a must before packaging, and even a small amount of moisture inside the case can cause mold and unpleasant odors that can be difficult to remove, and it is better to dry the boat in the shade, as direct sunlight accelerates the aging of the material and can cause deformation.
How to keep a boat in winter?
The ideal storage area is a dry room with a temperature of -10 to +30 degrees, the boat can be stored in a pumped state (suspended) or deflated, but not folded into tight cloths, it is recommended to lay out and ventilate the product every six months.
Periodically check the condition of the valves and seams. To clean, use a soft sponge and soap solution. Abrasive cleaning agents, solvents, gasoline and chlorine-containing substances are strictly prohibited to use, as they destroy the protective layer of PVC.
- 🧼 Wash the boat with a soft sponge with soapy solution after each exit.
- ☀️ Dry the product only in the shade, avoiding direct sunlight.
- 📦 Keep it straightened or loosely rolled, avoiding sharp folds.
If you find a small puncture or cut, do not delay repair. Use a remix, included in the standard equipment, or special glues for PVC. Quality repair allows you to fully restore the tightness and strength of the damaged area.
Security and registration at GIMS
Safety issues on the water are regulated by rules, violation of which can entail fines and, more importantly, a threat to life. According to Russian legislation, small vessels weighing more than 200 kg or with an engine of more than 8 kW (about 10.88 hp) are subject to registration with the GIMS.
Always check the weather forecast before you go out. A inflatable boat has a high sailing speed, and a strong side wind can quickly blow a light vessel into open water or dangerous objects. An anchor and an anchor shaft at least three depths long is a mandatory safety requirement.
The presence of life jackets in the size of each passenger is not just a formality, but the only guarantee of survival in the event of a boat tipping over.
It's also important to keep track of the attachments, the trunks must be securely secured, and the motor fasteners must be checked before each engine start, and losing the motor due to a poorly twisted nut is a frequent and unpleasant situation in water bodies.
⚠️ Warning: Driving a boat while drunk is equivalent to driving a car and entails administrative liability and heavy fines.
Don't neglect the rules of behavior on the water: observe the speed limit near the shore, give way to large boats and do not create dangerous situations for other vacationers. Remember that water does not forgive mistakes.
Frequently Asked Questions (FAQ)
Can I repair the PVC boat on my own?
Yes, small punctures and cuts up to 3-5 cm long can be sealed by yourself using a remix and a special glue for PVC (usually polyurethane). It is important to degrease the surface and observe the temperature regime of gluing. Serious damage to valves or seams is better entrusted to professionals in the service center.
What pressure should be in the cylinders?
The operating pressure in cylinders is usually 0.2-0.25 atmosphere (about 200-250 mbar), the exact values are always indicated in the product passport or on the labeling of the valve, and the excess pressure is dangerous by rupturing the seams, especially in hot weather.
How long does the boat dry before packing?
Drying time depends on the weather, but on average takes 2 to 4 hours outdoors in the shade, the boat should be completely dry to the touch, especially at the joints of slugs and cylinders, packaging wet products is guaranteed to lead to mold.
Do I need to register a boat with a 5 hp engine?
Not if the weight of the equipped boat together with the engine does not exceed 200 kg. Motors with a capacity of up to 10.88 hp (8 kW) and boats up to 200 kg are not subject to mandatory registration with the GIMS, but the rules of navigation and safety requirements apply to them in full.
How to clean the boat from oil or oil?
You can't use aggressive chemicals. You can try to gently remove the stains of oil with an absorbent napkin and then rinse them with soap solution. If you've eaten the oil, you should contact a specialized service, because trying to wipe it with solvent can damage the PVC protective layer.
